If you get a chance check out the factual horror story "The tale of the Radioactive Boy Scout" in the March 1999 issue of Reader's Digest on page 87. You will flip out! Th' wife tipped me off about this one.

It seems this kid made a significant neutron source from various commonly available radium and americium sources. He left a lot of hot debris in his wake and the EPA and NRC showed up at his home in moon suits and managed to load up 39, 55 gallon drums of rad waste from his little shed and back yard!!!
